摘要
针对远距离低信噪比条件下视觉传感目标检测困难的问题,设计并实现一种多传感器下的基于动态时空特性软硬协作决策的目标检测系统。系统以FPGA控制模块作为核心模块,主要用于传感器图像信息的采集、传递、存储以及控制。利用链路口发送模块对传感器信号进行转换和缓存。将USB设备作为整个系统的基础设备,主要负责整个系统信号数据的传输。通过片内存储器对系统的程序及数据进行保存,有效实现目标检测。软件设计过程中,引入动态时空特性下的软硬协作决策机制,并详细分析,给出目标检测的程序代码,仿真实验结果表明,所提系统具有很高的可靠性和实用性。
Since it is difficult to detect the remote vision sensing targets under the condition of low SNR,a multi-sensor target detection system based on the hard and soft collaborative decision with dynamic time-space characteristic was designed and implemented. The FPGA control module is adopted as the core module of the system,which is mainly used for the sensor image information acquisition,transmission,storage,and control. The delivery module at link port is used for sensor signal conversion and cache. The USB devices serve as the basic ones of the whole system to take charge of signal data transmission of the entire system. The on-chip memory is used to store the program and data of the system to achieve target detection effectively. In the process of software design,the hard and soft collaborative decision-making mechanism under dynamic space-time characteristics was introduced. A detailed analysis and the program code for target detection are o given. The simulation results show that the proposed system has high reliability and practicability.
